owhile

Profile-driven content gates. It checks whether a body of content is safe for the audience you declared it for. Every audience rule lives in a JSON profile; the gate code never changes. The same code gates a pre-reader safeguarding bank and an adult compliance bank without a line differing — only the profile does.

What this is not. It is not a game engine and not a library of playable mechanics. A mechanic here is a declaration — a verb name, a map of what each field is for, and structural rules — not code you can run. Declaring your own needs no permission and the gates will enforce it, but nothing in this package renders or plays anything. Gating a mechanic and playing one are different problems and only the first is solved.

Built for Owhile, where creators publish interactive experiences.

Install

pip install owhile
owhile --version

The shape of it

owhile init                                   # write a starting profile
owhile profile check                          # is it valid, and could it be listed?
owhile template --mechanic reflect --out sheet.csv
owhile build --sheet sheet.csv --out bank.ndjson
owhile check --report report.json

What it actually does

Five gates run over every item, and each reports pass, fail or could_not_run — so a gate that could not run is never mistaken for one that passed:

• role_totality — every scalar in an item has a declared role. A field nobody declared is a finding, not a shrug.
• invariants — your structural rules, declared per mechanic and validated at load, so a rule the gate cannot execute is refused before any content is read rather than crashing once per item.
• permissions — an audience may only use the mechanics it permits.
• budgets — reading length, counted in grapheme clusters rather than code points. A cap calibrated on English is a much harsher rule in Devanagari.
• resources — a cited helpline or policy reference must match your registry, and a correct citation is matched at its own full length before any hunt for a wrong one.

The report binds its verdict to a digest of the content and to a digest of the code that produced it, so a verdict cannot outlive either.

Declared, never inferred

The design rule the whole thing turns on. Meaning is declared in your profile and never guessed from prose: which side of a choice is affirming, which text is a myth being struck rather than an assertion, how old your youngest reader is. Earlier code inferred the affirming side by regex-matching an English label and painted the negative side green on sixteen live consent scenarios. A declared field cannot be wrong that way — it can only be absent, and absence blocks.

min_age has no default for the same reason. A profile without one is valid and its content gates clean; it is listing that is blocked. Silence is never read as adult.

Reporting a problem

https://github.com/Owhile/owhile-web/issues

Do not paste the output of owhile check, and do not attach files. A blocked run prints your item text verbatim, and a public issue cannot be un-published. Describe it in words — rule names and counts are fine, finding text is not. Anything that cannot be said in public has a private route linked from that page.

Status

0.1.1, and honest about it. The gates, the profile loader, the authoring loop and the report format are built and tested — 217 tests, mutation-tested, and proven across a 29,365-item corpus in two opposite audiences. The owhile command wrapping them is new in this release and has had far less use than the code underneath it. Listing on Owhile is not open yet: the eligibility rule and the digest binding are decided and enforced, and there is no submission path at all.

Known limits are documented rather than hidden, at https://owhile.vercel.app/creators/gates.md.
